A recipe for dense, fudgy brownies infused with the flavor of banana bread, topped with a rich brown butter frosting.

Ingredients

Scale
  • 1 cup (2 sticks) unsalted butter, plus 2 tablespoons for frosting
  • 1 1/2 cups granulated sugar
  • 3/4 cup packed light brown sugar
  • 4 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup mashed very ripe bananas (about 2 large)
  • 1 1/4 cups all-purpose flour
  • 1/2 cup unsweetened cocoa powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 cup semi-sweet chocolate chips, divided
  • 1/2 cup powdered sugar, for frosting
  • 2 tablespoons milk or cream, for frosting

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and line a 9×13 inch baking pan with parchment paper, leaving an overhang on the sides.
  2. Melt 1 cup of butter in a saucepan over medium heat. Continue cooking, stirring occasionally, until the butter foams and brown bits form at the bottom and it smells nutty. Remove from heat immediately and pour into a large bowl.
  3. Whisk the granulated sugar and brown sugar into the melted butter.
  4. Whisk in the eggs one at a time until fully incorporated. Stir in the vanilla extract and mashed bananas.
  5. In a separate bowl, whisk together the flour, cocoa powder, baking soda, and salt.
  6. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix. Fold in 3/4 cup of the chocolate chips.
  7. Spread the batter evenly into the prepared pan. Sprinkle the remaining 1/4 cup of chocolate chips over the top.
  8. Bake for 30 to 35 minutes, or until a toothpick inserted near the center comes out with moist crumbs attached, not wet batter.
  9. Let the brownies cool completely in the pan on a wire rack.
  10. Prepare the frosting: Melt the remaining 2 tablespoons of butter until browned, similar to step 2. Let it cool slightly.
  11. Whisk the cooled brown butter into the powdered sugar until smooth. Add milk or cream one teaspoon at a time until you reach a spreadable consistency.
  12. Spread the brown butter frosting evenly over the cooled brownies before cutting into squares.

Notes

  • Use bananas that are heavily spotted or nearly black for the best banana flavor and moisture.
  • For extra fudginess, slightly underbake the brownies by 2-3 minutes.
  • Chill the brownies for 30 minutes after frosting to help the frosting set before slicing.
